Viscount Hampden

Viscount Hampden is a title that has been created twice, once in the Peerage of Great Britain and once in the Peerage of the United Kingdom. The first creation came in the Peerage of Great Britain in 1776 for the diplomat and politician Robert Hampden, 4th Baron Trevor. The title of Baron Trevor, of Bromham, had been created in the Peerage of Great Britain in 1712 for his father, the lawyer Sir Thomas Trevor. Both titles became extinct in 1824 on the death of the first Viscount's second son, the third Viscount.

The viscountcy was revived in the Peerage of the United Kingdom in 1884 when the Liberal politician and former Speaker of the House of Commons, Sir Henry Brand, was created Viscount Hampden, of Glynde in the County of Sussex. Brand was the second son of Henry Trevor, 21st Baron Dacre and in 1890 he succeeded his elder brother as the twenty-third Baron Dacre. His son, the second Viscount, represented Hertfordshire and Stroud in Parliament and served as Governor of New South Wales. On the death in 1965 of his grandson, the fourth Viscount, the barony of Dacre fell into abeyance between the late Viscount's daughters Hon. Rachel Leila Brand and the Hon. Tessa Mary Brand (the abeyance was terminated in 1970 in favour of Hon Rachel Leila Brand; see the Baron Dacre for more information). The viscountcy passed to the Viscount's younger brother, the fifth Viscount. As of 2014^[update] the title is held by the latter's son, the sixth Viscount.
